When maintaining networks, it is often an expedient thing to do to run a transparent proxy. By transparent proxy I mean a proxy that 'hijacks' outgoing connections and runs them through a local service. Specifically I run a linux firewall with squid configured so that all tcp/ip connections fowarded on port 80 are proxied by squid.

This is achived using the iptables 'nat' table, using IPv4.

But iptables for IPv6 does not have a 'nat' table, so I cannot use the same implementation. What is a technique I can use to transparently proxy traffic for IPv6 connections?

(this question has still not been answered adequately yet, a year on)
